Spectral Optimization Problems Controlling Wave Phenomena
… problems are formulated as PDE-constrained optimization problems to find the material arrangement that maximizes an objective function which expresses the desired behavior. The PDE constraint describes the relationship between the material and the phenomena of interest. The focus of this …

Enabling rApp in 5G O-RAN: An Spectral Optimization (SO)rApp Use Case
… onboarding to deployment and execution, using a spectral efficiency op- timization use case to illustrate the process. The study develops and integrates a Spectrum Optimization (SO)rApp employing Reinforcement Learning (RL) techniques, specifically a Deep Q-Network (DQN) model, within the O-RAN …

Forensic Discrimination, Age Estimation, and Spectral Optimization For Trace Detection of Blood On Textile Substrates Using Infrared Spectroscopy and Chemometrics
… PCR (iPCR) was used to locate the optimal spectral regions associated with the changes due to blood aging.</p> <p>The sampling and collection of spectra was evaluated in order to decrease the spectral variation and enhance the discriminating power. High discrimination power is important so …

Investigating optimum wavelength(s) for growth of Lactuca sativa, L. using tunable LED sources and developing thin-film filters for glass greenhouses
… to approximately 14.7%) can be attained by using spectrally optimized illumination, instead of white light illumination. The resultant 9-layer thin-film filter was then fabricated in ESRI’s Clean Room using the E-Beam Evaporation system, with a balanced and symmetrical combination of ZnS, Al2O3 …

Asymptotically optimal shapes for counting lattice points and eigenvalues
"In Part I, we aim to maximize the number of first-quadrant lattice points under a concave (or convex) curve with respect to reciprocal stretching in the coordinate directions. The optimal domain is shown to be asymptotically balanced, meaning that the optimal stretch factor approaches 1 as the …
